BRACELET.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed. November 23, 1907. Serial No. 403,544.

T 0 all whom it may concern:

Be it known that I, EDWARD L. ANDERSON, a citizen of theUnited States, and residing in the town of Attleboro, in the county of Bristol and Commonwealth of Massachu setts, have invented certain new and useful Improvements in Bracelets, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof.

My invention relates to bracelets and particularly to adjustable bracelets. Its object is to produce an expansive adjustable bracelet simple in construction and of such thickness as will facilitate its use upon the arm.

Referring to the drawings, like characters denote like parts in all the figures.

Figure I shows a sectional view of the bracelet contracted or closed; Fig. II shows the same expanded or opened; Fig. III is a View of a box member; Fig. IV shows the back-plate; and Fig. V the back-plate applied to the box before fastening.

The bracelet consists of a series of boxes or shells 1 arranged substantially parallel with each other. The alternate box members are connected by a composite member pivotally attached to the opposite ends of the boxes and passing through the interior of the intervening box member. This composite member consists of arms 2 and 2 pivotally attached to and projecting from the opposite ends of alternate box members and entering the intervening box member through apertures 5 in the adjacent sides. Within the intervening box lies a spring 3 which joins together the ends of the two entering arms 2 and 2. The box 1 has, besides the apertures 5 already mentioned, other apertures 6 at its ends which receive the arms2 and 2 at their pivot joints. The back-plate 4 is made to fit the interior of box 1 and serve partly as a cover therefor. It is fitted with supports 7 which raise it from the floor of the box and measures to a large extent the thickness of the finished bracelet. It is also fittedwith projections 8 so located that they serve as pivots when the back is applied to the box and pass through the hole 8 in the arms 2 and 2' thereby forming a pivot joint. The bracelet is finished by turning the edge 9 over upon the back-plate 4 to hold it firmly in place.

WVhen the parallel box members of the bracelet are drawn apart the arms 2 and 2 are withdrawn from the interior of the adjacent box through the apertures 5 and the spring 3 is expanded. The contractility of the spring tends to draw the arms 2 and 2' into the box through the apertures 6 and bring the parallel box members nearer together.

Having described my invention, what I claim is 1. An adjustable bracelet consisting of a series of boxes; oppositely extending arms pivotally attached to the ends of each box; a spring uniting the opposite arms of alternate boxes.

2. An adjustable bracelet consisting of parallel boxes; arms pivotally attached to the ends of each box; a spring uniting the opposite arms of alternate boxes with the intervening box.

3. An adjustable bracelet consisting of parallel boxes; an arm pivotally attachedto one end of each box and entering an adjacent box; an arm pivotally attached to the other end of the box and entering the opposite adjacent box; a spring uniting the ends of the arms within the box.

4:. An adjustable bracelet consisting of a series of boxes and elastic members connecting the opposite ends of alternate boxes.

5. A bracelet composed of a plurality of units, connecting links pivotally secured at one end in the units, and spring elements in the units each connecting the free ends of links on the adjacent units, as described.

6. In a bracelet, a box provided with apertures in its sides; arms projecting through some of the apertures and provided with holes within the box; a back-plate fitted with supporting-flanges and adapted to set within the box; pivotal flanges upon the plate ada ted to enter the arm-holes; a projecting e ge upon the box adapted to overlap the back-plate.

7 In a bracelet, one member consisting of a box provided with apertures in its sides; a tures and hinged to the pivot flanges of the back-plate set in the box provided with adjacent member. s t 10 supporting flanges and with pivot flanges In Witness whereof I affix my name in the and a projecting edgeprovided upon the "presence of tWo Witnesses.
